Technical Field
[0001] The utility model belongs to the technical field of parts applicable to generators, and particularly relates to a chimney assembly. Background Art
[0002] When using a handheld soil sampling drill to conduct soil and surface matrix investigation and sampling in the wild, a generator needs to be connected to provide a power source. In currently commonly used generators, the length of the exhaust port of the muffler is relatively short and is arranged close to the bracket of the generator. After the generator works for a long time, the soot and heat ejected from the exhaust port will come into contact with the engine bracket during the dissipation process. Since the engine bracket is usually made of metal and has good thermal conductivity, it is easy to absorb and transfer heat, resulting in the bracket becoming hot. When the staff is conducting sampling operations, if they are not careful, they may come into contact with the hot bracket or the exhaust port, which is not only likely to cause burns, but also if they are close to the generator, the soot and hot air discharged from the exhaust port are likely to be directed at the staff, causing discomfort and even endangering the health of the respiratory system. Therefore, it is very necessary to design an exhaust component for installation at the exhaust port to solve the discomfort caused by the soot. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The present utility model will be further described below with reference to specific illustrations.
[0020] Please refer to Figure 1 and Figure 2, the present utility model provides a chimney assembly for installation on a generator. The generator includes a bracket 100, a generator set 110 disposed on the bracket 100, and a muffler 200 connected to the generator set 110. This chimney assembly includes a chimney mechanism 300 detachably installed on the muffler 200. The chimney mechanism 300 includes a fixing mechanism 310 detachably connected to the bracket 100, an L-shaped extension pipe 320 connected to the fixing mechanism 310, and a heat-insulating outer cover detachably connected to the outside of the extension pipe 320. One end of the extension pipe 320 is detachably connected to the smoke exhaust port 210 of the muffler 200, and the port of the other opposite end is higher than the top surface of the bracket 100 and away from the bracket 100. The smoke exhaust port 210 is connected to the extension pipe 320, and the extension pipe 320 is of an L-shaped structure, which can guide the soot and heat discharged from the smoke exhaust port 210 to a farther place away from the bracket 100, avoiding the bracket 100 from heating up and causing scalding. And the port of the L-shaped extension pipe 320 for discharging soot and heat is located above the bracket 100, and the soot and heat are dissipated upward. Therefore, even if the staff approaches the bracket 100, the smoke exhaust port will not be aligned with the staff for smoke exhaust, which can avoid causing discomfort or affecting the sampling work of the staff. The heat-insulating outer cover provides high-temperature heat insulation protection for the extension pipe 320, and even if there is an accidental touch during operation, it will not cause scalding.
[0021] The fixing mechanism 310 includes a fixing block 311 provided with a fixing groove 312, a fixing screw 313 screwed to the fixing block 311 and the first end of which can enter the fixing groove 312, and fixing clamp blocks 314 distributed in the fixing groove 312 and connected to the first end of the fixing screw 313. The second end of the fixing screw 313 is connected with a holding part 315 distributed above the fixing block 311, and the outer periphery of the holding part 315 is provided with anti-slip lines. The fixing groove 312 clamps the bracket 100 inside. By rotating the fixing screw 313, the bracket 100 is clamped by the fixing clamp blocks 314, and the chimney mechanism 300 is stably and firmly connected to the bracket 100, enhancing the firmness of the connection of the chimney mechanism 300 during the vibration of the generator.
[0022] The extended pipe 320 includes a first pipe body 321 with a first end clamped to the smoke exhaust port 210 and arranged parallel to the ground, an arc pipe 322 connected to the second end of the first pipe body 321, and a second pipe body 323 with a first end connected to the arc pipe 322 and arranged perpendicular to the ground. The outer wall of the first pipe body 321 is connected to the fixing mechanism 310 through a connecting rod 3210. A plurality of connection holes capable of being screwed with the connecting rod 3210 are provided on the outer periphery of the first pipe body 321. According to the actual use situation, the connection position between the fixing mechanism 310 and the extended pipe 320 can be adaptively changed. After the position of the fixing mechanism 310 is changed, the extended pipe 320 can also be fixed in a state where the smoke outlet port faces the ground. A high-temperature silica gel ring (not shown in the figure) is provided inside the first end of the first pipe body 321, and the high-temperature silica gel ring can improve the airtightness at the connection. When the anti-slip assembly is installed at the position of the smoke exhaust port 210, the first pipe body 321 is clamped to the smoke exhaust port 210, and the fixing mechanism 310 is connected to the bracket 100. On the basis of the clamping of the first pipe body 321 to the smoke exhaust port 210, the connection stability is further enhanced to prevent the clamped first pipe body 321 from slipping off due to vibration.
[0023] Please refer to Figure 3 , the second end port of the second pipe body 323 is defined as a smoke outlet 3231. A ring platform 3230 is provided on the outer wall of the second pipe body 323 and distributed around the outer periphery of the second pipe body 323. The ring platform 3230 is arranged adjacent to the smoke outlet 3231, and a rainproof mechanism 400 for preventing rain from entering the smoke outlet 3231 is detachably connected to the ring platform 3230. The rainproof mechanism 400 includes a screw hole vertically penetrating the ring platform 3230, a connecting screw 410 screwed with the screw hole, and a rainproof cover 420 connected to the upper end of the connecting screw 410 and distributed at the smoke outlet 3231. In the top view projection plane, the rainproof cover 420 can completely cover the smoke outlet 3231. The axis of the smoke exhaust port 210 is parallel to the ground, so the discharged soot and heat are easily directly directed at the staff. When the first pipe body 321 is installed on the smoke exhaust port 210, in the L-shaped extended pipe 320, the axis of the second pipe body 323 is perpendicular to the ground, and the smoke outlet 3231 faces upward and no longer discharges smoke at people, and the discharged soot and heat will be away from the bracket 100 to avoid scalding the staff. And in order to start the generator normally, the diameters of the first pipe body 321, the second pipe body 323, and the arc pipe 322 are all larger than the inner diameter of the smoke exhaust port 210. When the smoke outlet 3231 faces upward, there is a rainproof mechanism 400 for rain protection at the upper end of the smoke outlet 3231, which can prevent rain from pouring into the extended pipe 320 and causing damage to the generator. And by rotating the connecting screw 410, the distance between the rainproof cover 420 and the smoke outlet 3231 can also be adjusted, which is flexible and practical.
[0024] The heat insulation outer cover includes an outer cover body 330 whose shape is adapted to the extended pipe 320 and can be detachably connected to the extended pipe 320, and a heat insulation layer 340 arranged inside the outer cover body 330. The outer cover body 330 includes a first cover body 331 and a second cover body 332 hinged on one side, and the other opposite sides of the first cover body 331 and the second cover body 332 are detachably connected by a plurality of positioning mechanisms 500. Please refer to Figure 4 , the positioning mechanism 500 includes two side lugs 510 arranged on the edges of the first cover body 331 and the second cover body 332 and corresponding to each other, positioning screw holes respectively opened on the side lugs 510, and positioning bolts 520 screwed with the positioning screw holes. Open the hinged first cover body 331 and second cover body 332, and conveniently and adaptably sleeve the extended pipe 320 inside the first cover body 331 and the second cover body 332. Then the first cover body 331 and the second cover body 332 approach each other, and the first cover body 331 and the second cover body 332 are locked by the positioning bolts 520. One end of the outer cover body 330 after installation is adjacent to the connecting rod 3210, and the other end is adjacent to the annular platform 3230. The most easily touched part by the staff is protected by the outer cover body 330 against heat and scald, improving safety performance. Moreover, the detachable heat insulation outer cover can also be used for heat insulation protection of other pipes with matching shapes, and can be recycled to save resources.
[0025] The heat insulation layer 340 includes a high-temperature silica gel layer 341 fixedly connected to the inner wall of the first cover body 331 or the second cover body 332, and a heat insulation cotton layer 342 fixedly connected to one end of the high-temperature silica gel layer 341 away from the first cover body 331 or the second cover body 332. After the heat insulation outer cover is installed, the heat insulation cotton layer 342 contacts the outer wall of the extended pipe 320, and the heat is blocked by the high-temperature silica gel layer 341. Even if a staff member touches the first cover body 331 or the second cover body 332, there will be no risk of scalding.
[0026] This chimney assembly: First, install the chimney mechanism 300 at the smoke exhaust port 210 of the muffler 200. The smoke outlet 3231 in the L-shaped extension pipe 320 of the chimney mechanism 300 is far from the bracket 100, extending the smoke exhaust flue of the muffler 200. Therefore, it can avoid the bracket 100 from heating up and scalding the staff. Moreover, even if the staff approaches the bracket 100, the smoke outlet 3231 faces upward, and the exhausted soot and heat no longer aim at the staff, so as to prevent the soot and heat from causing discomfort to the staff and reducing the damage to the respiratory system. Second, connect with the bracket 100 through the fixing mechanism 310, and connect the first pipe body 321 with the smoke exhaust port 210, so that the chimney mechanism 300 can be stably and firmly installed together with the bracket 100 and the muffler 200 to avoid falling off due to the vibration of the generator. Third, the outer cover 330 covers the outside of the extension pipe 320 for heat insulation protection to prevent scalding. The heat insulation layer 340 in the first cover 331 and the second cover 332 is easy to manufacture and low in cost. By loosening the positioning bolt 520, the first cover 331 and the second cover 332 can be disassembled from the extension pipe 320, and the removed heat insulation outer cover can be reused.
